Explore the most popular trails in Great Valley Grasslands State Park with hand-curated trail maps and driving directions as well as detailed reviews and photos from hikers, campers and nature lovers like you.

Great Valley Grasslands State Park preserves one of few intact examples of native grasslands on the floor of the Central Valley. The park is part of the larger Grasslands Ecological Area (GEA) of federal, state and private lands all managed for wildlife values. The GEA represents the largest remaining contiguous block of wetlands in California. Several rare and endangered plant and animal species inhabit the park, including alkali sacaton, a native bunch grass, and the Delta button celery (Eryngium racemosum) a state listed endangered species found in the flood plain of the San Joaquin River. Biologists have also reported the California Tiger Salamander and endangered vernal pool fairy shrimp and tadpole shrimp. Springtime wildflower displays, fishing and wildlife watching attract visitors to this undeveloped park, which also encompasses the former Fremont Ford State Recreation Area.

Save this one for the late spring, while the grass is green and the high water has swept away all the litter and dried up brush. Or skip it altogether. I was very disappointed.

Not much but better to do in the summer than the others close by I've done. This one goes from a boat launch along a littered polluted river. But in this area there isn't much for trails...

Not a friendly summer hike. Full sun exposure along a gravel or dirt road. One place with a short little trail for my dog to get to the river but the San Joaquin is one of the most polluted in the state. In the spring or winter it would be much better with all the waterfowl but not this time of the year. Lots of hawks and coyotes...

Fail!! It was very dry and no shade along the trail whatsoever. I was hoping that there was a way down to the river for my dogs to drink water, but there was none. Luckily I had my own water. The only reason I gave it 2 stars is because its good to just go for a jog. Its flat, dogs don't have to be on a leash. I also saw allot of fishermen.
